Please check that the From: line contains a valid email address. After a delay of up to one day, you should receive an acknowledgment at that address. Please write in English if possible, as the Emacs maintainers usually do not have translators for other languages. Please describe exactly what actions triggered the bug, and the precise symptoms of the bug. If you can, give a recipe starting from `emacs -Q': M-x query-replace is case insensitive by default. You may sometimes want to replace a string with another differing only in case, for example changing 'aaa' to 'Aaa'. But query-replace prompts for all cases where a case-insensitive match for 'aaa' is found, even those that already equal the destination string. Here are the keypresses starting from 'emacs -Q' to reproduce: a a a RET A a a RET ESC O A ESC O A ESC % a a a RET A a a RET y I suggest that if the search and replacement strings differ only in case, then Emacs should prompt only where there is a real choice to be made. When the match of 'Aaa' is highlighted it makes no difference whether you answer y or n; so Emacs should not waste the user's time asking. This does mean that the matches highlighted by query-replace differ from those you would find with a normal case insensitive search, in these specific circumstances where the search and replacement strings differ only in case. I think that is a fair tradeoff. If Emacs crashed, and you have the Emacs process in the gdb debugger, please include the output from the following gdb commands: `bt full' and `xbacktrace'.
